The Part 70 Low-emitting Facility (LEF) General Permit is primarily intended for businesses with high potential emissions and low actual emissions that began operating without an air permit. Examples of businesses that are likely to apply are auto-body shops, metal fabrication facilities, cabinet shops, other businesses that coat or paint, and facilities that have engines, boilers or tanks on site. However, anyone can apply. Target facilities may have:
- constructed a major source under the New Source Review (NSR) program and/or;
- constructed and operated a major source of hazardous air pollutants.
If a facility has potential emissions that exceed major source thresholds for either program, they will likely be:
- subject to BACT-equivalent requirements;
- subject to major source NESHAPs; and
- unlikely to qualify for a Registration Permit.
The Low-emitting Facility permit includes BACT-equivalent requirements, and major and area source NESHAPs.

Frequently asked questions
- Its flexibility allows you to make changes and modifications at your facility easily
- It’s less expensive than an individual permit
- It includes a range of commonly applicable federal requirements
- It accommodates a wide range of industry types
The Part 70 Low-emitting Facility General Permit is primarily intended for businesses with high potential emissions and low actual emissions that began operating without an air permit. Examples of businesses that are likely to apply are auto-body shops, metal fabrication facilities, cabinet shops, other businesses that coat or paint, and facilities that have engines, boilers, or tanks on site. However, anyone who meets the qualifications can apply.
If you started operating a facility without a permit and your potential to emit is above certain thresholds, you no longer qualify for a Registration Permit. Here’s why: Once you have begun operation you are stuck with using your maximum, unrestricted potential to emit to define what type of permit you must get. Potential to emit is the maximum amount of a pollutant that a facility could possibly emit if it operated at maximum capacity for 24 hours a day and 365 days a year.
If your facility has a potential to emit over the Prevention of Significant Deteriorations threshold for any individual criteria pollutant (100 or 250 tons per year depending on your source category) and you did not get a permit before starting operation, then you are required to get a Part 70 permit that contains emission limits that are equivalent to Best Available Control Technology (BACT) limits. These are referred to as BACT-equivalent limits. The Low-Emitting Facility Permit contains the limits that fulfill this requirement. If your facility qualifies for the Low-emitting Facility Permit, then that saves you the time and money that it usually takes to decide what these limits should be for your specific facility.
If your facility is over the threshold of 10 tons per year for an individual hazardous air pollutant or 25 tons per year for the total amount of hazardous air pollutants, then you must comply with any National Emission Standard for Hazardous Air Pollutants (NESHAP) that applies to you, and you are required to get a Part 70 permit. The Low-Emitting Facility Permit is a type of Part 70 permit, and it contains NESHAPs that are common to coating and combustion operations.
Yes, anyone can apply. However, the Low-emitting Facility General Permit is intended for existing facilities that have been operating without a permit and have very low actual emissions. If you apply for this permit you must be able to stay under the limits of the permit. You will have to apply for an individual permit if you ever need to increase your emissions beyond the limits of the Low-Emitting Facility Permit.
If you are applying for a permit for construction of a new facility that will have low actual emissions, and construction has not yet started, there are other permit options that may be more appropriate, such as a Registration Permit.
Yes, this permit will expire after five years. Since this is a General Permit, the five year time period will begin when the first permit is issued. This means that everyone who receives this permit will have the same expiration date for their permit. You will have to apply for the next generation of the general permit 180 days before the expiration date.
As long as you apply for the next version of the general permit on time, then your current permit will continue to be valid until the MPCA issues you a new permit. An application fee for a General Permit (currently $1,140) is required.
The main reasons to apply for this permit are to save time and money. The process of applying for a Part 70 Individual permit is time-consuming for everyone because an individual permit is tailored for your specific facility. Additional time is necessary if Federal BACT-equivalent limits or NESHAP requirements must be included. In comparison, the Low-Emitting Facility Permit is pre-written to cover a range of operating scenarios and applicable Federal requirements, which streamlines the process. The time savings are reflected in the cost of the permit. The table below compares the Low-Emitting Facility Permit fees with two types of Part 70 Individual Permits.
|Permit Type||Part 70 Low-Emitting Facility General Permit||Part 70 Individual Permit, major for PSD (requires BACT review), with two NSPS Reviews||Part 70 Individual Permit, major for HAPs with a NSPS and a NESHAP|
|NSPS or NESHAP||$0||$5,700||$5,700|
|Limits to Remain Below a Threshold||$0||$2,850||$2,850|
Furthermore, with the Low-Emitting Facility Permit facilities can make changes and modifications without applying for a permit amendment, as long as they continue to comply with the limits and requirements of the permit.
The best way to answer these questions is to read over the application forms on this website starting with the Handbook and Application Instructions. The forms will guide you through a series of questions that will help you determine if you qualify for this permit.
Additional information is available at the links below; The MPCA resources listed below can provide some assistance in filling out these forms. If you need further assistance, you may need to contact a consultant.
A link to electronic versions of the permit and the technical support document are provided below. Please be aware that the general permit is designed to be flexible. It incorporates requirements for a wide range of operations, and allows a Permittee to make changes to their facility without requesting a modification to the permit. This flexibility results in a lengthy permit.

- Final Technical Support Document (4/30/15)
Because of the permit length, and because it is unlikely that all of the permit content will apply to your facility, a link to a Word document that you can download, edit and use as a tool for compliance is also provided. The Word document contains an index to help you navigate through the permit by holding the CONTROL key, and clicking on the section you want to see.
You could use this document by deleting sections that you know do not apply to you, to make it easier to follow the requirements that do apply. Note that this is not your official permit. If you make any changes to your facility and think that other portions of the permit might apply, then you must refer to the official (entire) document.
The following are sections of the final permit. The purpose of providing the permit in this format is to enable users to access the permit in manageable parts, and to more easily disregard those sections of the permit that may not be applicable to a given facility.
